What We Do

MSD protects our community’s overall health and safety by providing clean waterways and by managing flood and drainage issues—24 hours a day, 365 days a year.

This is the job of about 600 MSD employees across the 376 square miles of the Louisville Metro* area. While we operate and maintain Louisville Metro’s sewer and floodwall systems, water quality treatment centers and flood pumping stations, MSD also invests in hundreds of infrastructure improvement projects each year and plants more than 1,000 trees and other plants to enhance water filtration and reduce runoff.

We also pride ourselves in educating and informing our community through dozens of outreach programs about protecting our waterways.
